Abstract
The availability, in the last few years, of low cost microcomputers and multichannel seismographs has made possible the application of high resolution, digital, seismic reflection profiling to Quaternary problems. Seismic analysis of the subsurface can provide continuous, two dimensional sections containing detailed structural and stratigraphic information. A review of the general principles of shallow seismic reflection methods includes the nature of seismic sources (the use of shotgun shells), the application of the ‘optimum offset’ method, data processing and the issue of site dependency. A brief overview is provided of seismic and sequence stratigraphy. Four case studies illustrate the application of reflection seismic profiling: (1) Champlain Sea sediments (Late Wisconsinan) on the flank of the Gatineau Hills near Quyon, Québec; (2) the definition of bedrock valleys beneath Pleistocene deposits near Shawville, Québec; (3) the fill of a linear depositional basin — Okanagan Valley, British Columbia; (4) the seismic signatures of topset and foreset beds, slope failures and a distributary channel of the Fraser River delta, British Columbia.
